Abstract
In the framework of the RD19 collaboration, a binary silicon pixel detector system has been tested in a magnetic field between −2 and +2 T. The spatial resolution was measured using a high-resolution silicon strip telescope as reference. A detection efficiency of 99.8% independent of the magnetic field was found. The magnetic field influences the amount of charge sharing between the pixels which, for the binary system, results in a change of the ratio of double hits to single hits. A simple model for the charge drift in silicon under the influence of a magnetic field was established and the model predictions are in good agreement with the experimental results.
